They are insanely accurate in most developed countries, to the point of listing individual trees and boulders at times, and that’s something OSM et all isn’t even trying to match.
The fact that this is up for debate in this thread kind of reinforces my point: this used to be something every hiker would know. Route finding is based on maps, printed (curated) guidebooks and talking to experienced hikers or guides.
We moved to a paradigm where the definition of knowledge is what is accessible by Google (either google itself or a searchable link). I can’t then really blame people for following down this route - but ultimately this is heading in a direction of lost knowledge.
We think, oh what a shame we are losing the traditional Maori navigation methods, but I guess the same is happening (at a much smaller scale!!!) to modern societies too.
